Water Tube Wet Back Packaged Gas Water Boiler

Hot water tube wet back packaged water boiler which is not equipped with no impact can cause demineralizer 1, the waste fuel boiler fouling occurs, resulting in poor heat transfer performance of heating surface, so that heat generated by the combustion of the fuel can not be timely delivered to the boiler water, but a large amount of heat is smoke away, resulting in exhaust gas temperature is too high, if the exhaust gas loss increases the thermal efficiency of the boiler will be reduced. In order to maintain the nominal parameters of the boiler, fuel must be increased, thereby wasting fuel. About 1 millimeter scale waste fuel ten percent. 2, the heat receiving surface is damaged due to deterioration of the heat transfer performance, fuel combustion heat is not quickly transmitted to the boiler water, resulting in the furnace and the flue gas temperature. Thus, the temperature difference on both sides of the heating surface increases, the metal wall temperature, a decrease in strength. Under pressure pot, bags and even blasting will occur. 3. Reduce heat boiler output due to the deterioration of the performance of boilers, need to consume more fuel to reach the nominal rate of evaporation. However, with the increase in the scale thickness, the volume of the furnace becomes large, the fuel consumption is limited. Therefore, it is possible to reduce the output of the boiler. 4, the corrosion damage to the metal: oxygen in the water, acid, base materials will corrode the metal surface of the boiler, it is thinned, recess or perforation, thus reducing the power of the boiler, seriously affect the safe operation of the boiler. 5, in addition to improper operation Priming outside, when the boiler water contains more sodium chloride, sodium phosphate, and silicides oil, boiling or evaporation process boiler water, boiler water occurs when soap and organic base when Teng because soda will produce compost. Foam liquid surface, formed soda pool. No softening, easily scalable. Due to the continuous evaporation steam, boiler of calcium, magnesium, high impurity concentration is 30-50 times that of natural water, fouling rate beyond our imagination, only six months to a year, from 1-2 mm.

How to judge whether the burning oil and gas boiler is extinguished or not?

The indication value of the negative pressure gauge of the fuel gas boiler furnace suddenly increases; the inside of the furnace becomes black, the flame is not seen by the fire hole; the burning sound of the furnace disappears; the fire monitor emits a fire extinguishing signal; the temperature and air pressure drop sharply, and the water level drops first and then rises. These are all flameouts. If the auxiliary fan accident causes a flameout, if the power supply of the induced draft fan or blower is interrupted, there will be an accident signal; if the fuel supply is interrupted, the boiler fuel or gas pressure will drop to zero.

Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, boiler flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot water tube wet back packaged water boiler of a 4.2MW for heating needs of the shopping center.

Water produced by the following factors: the temperature of the flue gas (91% in order to achieve thermal efficiency, the temperature of the flue gas needed to reach 170 ℃), where the total surface area of ​​the heat chimney, chimney and chimney material. Maintenance of the burner. Electric steam boiler and burner maintenance, repair after steam supply. Because the products of combustion will corrode the boiler, clean up carbon deposits, therefore, not allow the products of combustion in the boiler memory stay too long. 3, clean electric boiler essential content.
